Just got a Softbank Iphone 6S unlocked by IphoneUnlock. It took a quite long time (about 14 days) to get my Iphone unlocked, but I guess that the nature of unlocking Iphone from Japan. After I got the instruction mail, I got very excited and after following the guide, tadahhh... my phone is unlocked, now I can use whatever SIM card I want. Thanks a lot!
Thanx John! Yeap, Softbank Japan might cause some delays, but at the end we end up with an unlocked iPhone (Yours :D) . Enjoy your unlocked iPhone!
